Fuel 1003-50MBMB Center Cap
The 1003-50MBMB part number is the most important identifier when replacing this Fuel center cap. Fuel produced numerous center caps within the 1003-50 family, and similar-looking versions should not automatically be considered interchangeable.
If your existing cap is marked 1003-50MBMB, compare the diameter, height, finish, rear retention system, and overall profile to this replacement before ordering.
1003-50MBMB vs. 1003-50MB
1003-50MBMB and 1003-50MB should be treated as separate replacement center cap part numbers.
This 1003-50MBMB listing is specifically for the version featuring a matte black cap with a matte black Fuel logo. Do not assume another 1003-50 finish variation is identical simply because the base casting or reference number is similar.
For the best fit and appearance, match the complete suffix of your original center cap whenever possible.
Matte Black With Matte Black Fuel Logo
The 1003-50MBMB has an all-black appearance with a matte black cap body and matte black Fuel logo. This differentiates it from other Fuel center caps that use chrome, gloss black, contrasting, or other logo finishes.
Customers searching for a Fuel black-on-black center cap, Fuel matte black logo center cap, or Fuel all-black center cap should still verify the complete 1003-50MBMB part number before ordering.
Fuel 8x6.5 Center Cap
The Fuel 1003-50MBMB is designed for select Fuel wheel applications using the 8x6.5 bolt pattern and this specific center cap design.
The metric equivalent of 8x6.5 is 8x165.1. Customers may therefore see compatible wheel applications described as either 8x6.5 or 8x165.1.
Important: Not every Fuel 8x6.5 wheel uses 1003-50MBMB. Fuel manufactured many 8x6.5 wheels with different center bores, center cap depths, and retention systems.
Fuel 8x165.1 Center Cap
If you are searching for a Fuel 8x165.1 center cap, the 1003-50MBMB is a known replacement for select Fuel wheel applications.
Because many different Fuel wheel designs were offered in 8x165.1, the bolt pattern alone cannot determine center cap compatibility. Match the exact 1003-50MBMB number and physical cap dimensions whenever possible.
5-Inch Fuel Center Cap
This A2i Wheel & Tire center cap measures approximately 5 inches in diameter.
Diameter is an important fitment measurement, but it should not be used alone. Two Fuel center caps can have similar outside diameters while using different heights, retention clips, or mounting profiles.
4-Inch Tall Fuel Center Cap
The A2i Wheel & Tire 1003-50MBMB measures approximately 4 inches tall. This depth is especially important on 8-lug truck wheels because the cap must provide the proper clearance while still attaching securely to the wheel.
When replacing a missing center cap, compare both the 5-inch diameter and 4-inch height to your existing cap.
Fuel Snap-In Center Cap
The 1003-50MBMB uses a snap-in mounting design. The rear retention system attaches the cap directly to the compatible wheel center opening.
Before ordering, inspect the back of your original center cap and compare its retention clips, mounting diameter, height, and overall profile to the product photos.
1003-50 Reference Number
The base number 1003-50 may appear as an additional reference or casting number associated with this Fuel center cap family.
For this product, the complete 1003-50MBMB identification is more useful because the additional letters identify this specific black-on-black version.

How to Verify 1003-50MBMB Fitment
- Remove one of your existing Fuel center caps.
- Inspect the back for a molded, stamped, printed, or sticker part number.
- Look specifically for 1003-50MBMB or the base 1003-50 reference.
- Confirm that your original cap has a matte black body and matte black logo.
- Measure the cap diameter and compare it to approximately 5 inches.
- Measure the overall height and compare it to approximately 4 inches.
- Confirm that your existing cap uses the same snap-in mounting design.
- Compare the rear retention system to the product photos.
- Do not rely only on wheel bolt pattern or vehicle make and model.
Why Matching the Complete Part Number Matters
Fuel center caps can look nearly identical from the front while having different finishes, heights, mounting diameters, retention clips, and wheel applications.
With this cap family, the suffix is especially important. Match the complete 1003-50MBMB part number rather than relying only on the base 1003-50 number.
Important Vehicle Fitment Information
This center cap fits the wheel, not the vehicle. Chevrolet, GMC, Dodge, Ram, and other trucks using an 8x6.5 / 8x165.1 bolt pattern can be equipped with many different Fuel wheels and center caps.
An 8x6.5 vehicle does not automatically use this center cap. Your Fuel wheel must be designed for the 1003-50MBMB cap.
